Environmental Transport: Reaction and Interfacial Exchange

Understanding how pollutants and natural substances migrate through air, water, and soil is crucial for modern environmental engineering and science. This text-only course provides a clear, step-by-step guide to the physical and chemical principles governing mass transport, reactions, and phase exchanges in natural systems. You will start with core definitions of mass balance before exploring complex transport equations. By reading through practical scenarios, you will learn to predict how substances dissolve, react, and partition in the environment. What you'll learn: - Learn the foundational principles of advection, diffusion, and reaction kinetics. - Solve mass transport equations for dissolving species in aquatic environments. - Understand the mechanics of gas exchange across the air-water interface. - Analyze how chemicals partition between liquid and solid phases, including soils and suspended sediments. - Apply mathematical models to predict pollutant pathways and lifetimes in natural water bodies. The course begins with essential terminology and the governing equations of mass balance, then guides you through one-dimensional transport models, and finishes with multi-phase interfacial exchange dynamics. Designed for beginners in environmental science, hydrology, and civil engineering, this course requires only basic chemistry and algebra. Start reading today to build a strong foundation in environmental transport processes.
